Floorp is a Firefox-based browser with workspaces for separating tab sets. A separate panel sidebar and selectable layouts change how ordinary Firefox tabs appear. A workspace controls which group of tabs appears in one window. A Web Panel loads a site beside the main tab, while Split View places several ordinary tabs in one content area.
The Panel Sidebar is different from Firefox’s native sidebar. Floorp can use a horizontal tab arrangement or native vertical tabs. A multi-row layout creates another tab-bar path. These layout systems share space, so combining them can produce conflicts that one default tab bar never exposes.
Hidden workspace tabs remain open
Only one workspace appears in a window at a time, but tabs in inactive workspaces remain open in the background. Switching workspaces reduces visible clutter without necessarily reducing memory use.
A workspace can use a Multi-Account Container and can move into an archive with its tabs. Workspace structures can be shared inside the same profile, but that mechanism does not share the individual open tabs.
Initialize workspaces deletes custom workspaces and cannot undo the reset. Floorp moves their tabs into a new default workspace, so the pages survive while the names and organization do not. The Panel Sidebar workspace manager also omits some controls available through the toolbar popup.
Closing a Web Panel may leave it loaded
A Web Panel can store a container choice, width, zoom and a mobile user agent. The mobile user agent requests a mobile layout but cannot force a website to return one. Some extension pages also cannot render in the panel.
Closing a panel normally hides it without releasing its loaded state. Floorp unloads it on close only when the matching option is active, or when the user runs an explicit unload action. A long list of hidden panels can therefore keep more state than the visible sidebar suggests.
Deleting a panel has no undo path. Floorp Notes follows a separate route and can synchronize formatted notes and image attachments through Firefox Sync.
A split begins at the edge of the content area
Dragging a tab to an edge adds it to Split View on that side. Dropping it in the center moves the tab to a new window instead. Floorp builds this behavior on Firefox’s native Split View and supports a grid of up to four tabs under the documented limit.
The address-bar split control can add subdivisions or change the arrangement. Each pane still contains an ordinary tab. Closing or navigating that ordinary tab changes the pane content.
Vertical tabs compete for native sidebar space
Floorp replaced its older custom vertical tabs with Firefox’s native vertical tabs. The native design uses Firefox’s sidebar location and can conflict with Floorp sidebar configurations or custom CSS.
Multi-row tabs introduce another limit. Once the chosen row count fills, overflow changes to horizontal scrolling. Custom CSS can also conflict with tab-position settings. Those overrides and the selected position can therefore request incompatible layouts.
The portable build lacks Windows browser registration
Floorp Portable runs without the installer registration that Windows uses for a default browser. Normal Windows settings therefore cannot select it as the default. Copying the portable folder to another location does not add that registration.
The official portable page mentions third-party registration tools and a script only as unsupported workarounds used at the user’s risk. Installing the registered Floorp build is a different choice from forcing a portable copy into the Windows default-browser list.
